102 ARANEIDEA. 
metatarsi, with a thin scopula beneath the tarsi and the anterior half of the metatarsi, and a compact 
claw-tuft beneath the two terminal pectinated claws. 
Mawille of moderate length, rounded and broadest at their extremities, somewhat inclined towards each other 
over the labium, which is very short, transverse oblong, and a little narrower at the apex, the latter 
rounded. 
Sternum heart-shaped. 
Falces moderate in length and strength, a little divergent, prominent towards their base in front. 
Prusias nugalis, sp. n. 
Immature male, length 43 lines. 
The whole spider is of a yellow colour ; the cephalothorax perhaps rather darker than the rest, and clothed 
with pale hairs. The cephalothorax has a largish suffused blackish spot at the thoracic indentation, and 
the caput also has some slight dusky blackish markings. 
The eyes are on slight tubercles: the four centrals form a quadrangular figure, whose anterior side is the 
longest, and the other three sides equal. The fore central pair are separated from each other by slightly 
more than an eye’s diameter, and from the laterals by a very narrow interval, being almost contiguous ; 
they almost reach the anterior margin of the caput, leaving little or no clypeus. 
The legs and palpi are marked with small blackish spots and points, as also are the falces on their prominent 
portion. 
The abdomen is oval, yellow, thinly furnished with hairs. The upperside is marked with small black spots; a 
diffused, rather broad, somewhat reddish-brown band runs along each side of the median line, leaving a 
broad central longitudinal yellow band slightly spotted with black, the latter with a large, well-defined, 
angular prominent point on each side towards its fore extremity, thus forming a kind of cruciform 
marking ; the hinder part of this marking is formed by the coalition of the series of normal angular bars, 
diminishing in width as they run backwards. Spinners small and inconspicuous. 
Hab. Panama, Bugaba (Champion). 
RAMNHES, gen. nov. 
Nearly allied to Prusias. 
Cephalothorax a little broader than long; profile of caput slightly convexly curved from the anterior eyes to 
the thoracic junction ; lateral marginal indentations at the caput strong. Clypeus almost obsolete. 
Legs long, rather slender, 2, 1, 4, 3, furnished with long spines on the tibia and metatarsi, and a tolerably 
strong scopula beneath the metatarsi and tarsi, with a compact claw-tuft beneath the terminal pectinated 
tarsal claws. 
Falces moderately long, strong, straight, and a little prominent towards their base in front. 
Eyes occupying the whole width of the caput, in two transverse curved rows; the convexity of the curves 
directed forwards, and the anterior row slightly the longest and most curved. The four centrals form a 
quadrangular figure very slightly longer than broad. 
Mazxille short, broad, very nearly straight, broader at their extremities (where they are slightly rounded) than 
at their base. 
Labium very short, small, and almost semicircular in form. Sternum heart-shaped. 
Ramnes semotus, sp. n. 
Female (? adult), length 5 lines. 
The cephalothorax is pale orange-yellow, the caput marked above with distinct black lines and other less 
regular markings, the thorax with a few dusky black markings on the sides. The clypeus is almost 
obsolete, the middle anterior or fore central pair of eyes being close to the fore margin of the caput. 
The eyes are rather small and nearly equal in size, the fore centrals rather the largest ; those of the hinder 
row are separated by very nearly equal intervals, those of the fore central pair are rather further from 
each other than each is from the fore lateral eye on its side.
